Article ID: 112986


Updated On:


File Master Plus for IMS File Master Plus for DB2 for z/OS


This APAR introduces the OSPROTECT system parameter which specifies the operating system protection mode for unauthorized programs and users. With this apar applied, software must no longer reference the IHAPSA field PSASTAK because the PSASTAK is no longer the beginning of the normal FRR stack. PSACSTK is an existing pointer to the beginning of the normal FRR stack. Software that references PSASTAK must be converted to use PSACSTK as the pointer to the normal FRR stack.The PSASTAK is related to recovery management and the apar itself changes the definintion of the PSASTAK field in module IHAPSA  to PSACSTK and software continuing to reference PSASTAK can receive a S0C4. 

Is there any specific fix for the File Master Plus for MVS and for IMS products for the Meltdown mitigation fixes from IBM - APAR OA54807?


CA File Master installed in a z/OS 2.1, 2.2,or 2.3 environment with IBM APAR OA54807 applied.  


CA File Master does not reference the PSASTAK so there is no impact
